here is the problem.. i keep getting yes for the first part and then around 163 for the second part. please help.(adsbygoogle = window.adsbygoogle || []).push({});

Speedy Sue, driving at 31.5 m/s, enters a one-lane tunnel. She then observes a slow-moving van 105 m ahead traveling in the same direction as her at 5.10 m/s. Sue applies her brakes but can decelerate only at because the road is wet. Will there be a collision?

yes or no?

If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van and enter 0.00 for the time.
